Understood.  Do you have any specific suggestions as to how we could 
modify proposal 97 to codify a restriction, while still giving staff 
leeway to make exception for anyone who is clearly not trying to bend 
any rules?

I don't believe that finding a bunch of /24s on the transfer market will 
be allowed.  We'll find out more details soon when ARIN staff releases 
their implementation plan, but the policy says that the recipient of 
transferred space must "demonstrate the need for such resources, as a 
single aggregate, in the exact amount which they can justify under 
current ARIN policies."

Does that address your concern?
